If N2000 series switch has an earlier version of firmware (6.0.0.7 or 6.0.0.8 or 6.0.1.3), upgrade switch to the latest version of firmware 6.6.0.23 as it contains multiple bug fixes.

New CPLD version 20 is available in release 6.5.1.1 and later (6.6.0.23) for N2000 Series switches. After upgrading the switches to FW version 6.5.1.1 and later (6.6.0.21), the CPLD can be updated to version 20 from CLI using the command - "update cpld". To update CPLD on stack members, run - 'update cpld ' command from stack master. Please DO NOT power-cycle the switch when CPLD update is in progress. After CPLD update is complete, the switch will reset on it's own. Verify CPLD Version with the command - 'show version' from CLI after switch boot-up completes.
